Thanks for the PR.

I think the following should be updated to use languageOptions.sourceType if we are no longer setting parserOptions.sourceType:

https://github.com/DMartens/eslint.org/blob/fd870ab13462a53b84bb0b5d5ffb9f6aeed4f693/src/playground/components/configuration.jsx#L398-L401

Also, the following doesn't seem necessary if we are no longer using parserOptions.sourceType:

https://github.com/DMartens/eslint.org/blob/fd870ab13462a53b84bb0b5d5ffb9f6aeed4f693/src/playground/components/configuration.jsx#L526-L527

Right now on selecting @typescript-eslint/paser the Source Type option is empty, as #915 (comment) suggests to use the default value for sourceType, so can we also add (default) option on Source Type for tsparser as well like we have for espree?

Right now on selecting `@typescript-eslint/paser` the `Source Type` option is empty, as [#915 (comment)](https://github.com//pull/915#discussion_r2725504081) suggests to use the default value for `sourceType`, so can we also add `(default)` option on `Source Type` for tsparser as well like we have for espree?

Looks like we don't need separate lists of Source Type values for Espree and @typescript-eslint/paser?
